Abstract: 222,118. Pintacuda, C., and Frilli, U. Sept. 19, 1923, [Convention date]. Addition to 216,844. Vibration - dampers. - A shock absorber comprising arms formed at one end as friction discs and a spring acting on the discs and secured by a nut connected to one of the arms so that movement of the arms rotates the nut and increases the spring pressure on the discs, as described in the parent Specification, is modified by y providing the pivot pin s with a pin x adapted to engage inclines y on a collar w which is connected to one of the arms of the device, and is adjustable to suit the desired initial angle between them. The pin x, in the mean position of the arms engages the lowest parts of the inclines so that both opening and closing of the arms increases the pressure of the spring f on the discs by an amount determined by the shape and slope of the inclines. The initial tension of the spring f is adjusted by a nut v provided with an index 4, and a notched sector z rigid with the collar w effects .the adjustment of the inclines y with respect to the pin x. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a plain sector z gripped by a clip on the arm of the device. This subject-matter does not appear in the Specification as accepted.

Patent GB-483205-A (GB)
Title: Friction clutches
IPC: F16D13/02
Filed: 1937-08-12
Abstract: 483,205. Free-wheel clutches ; operating clutches. HARBERD, E. H. (Maschinenfabrik Weingarten vorm. H. Schatz Akt.-Ges.) Aug. 12, 1937, No. 22174. [Class 80 (ii)] A clutch for drawing presses comprises a nut 3, Fig. 1, threaded on the machine shaft 1 and urged by a spring 6 so as normally to clamp a driving flywheel 5, journalled on the shaft, between a friction facing 4 on the nut and a friction facing 9 on a member 8 fixed to the shaft, the relative dimensions of the two facings being such that the greater part of the drive is through the member 8, the facing 9 being carried by a rim portion which is resiliently connected to the hub portion of the member 8. The clutch is disengaged by moving a pawl 10, Fig. 3, into the path of a number of teeth 3a on the nut 3, the teeth being so disposed that the clutch can be disengaged at various stages of the power stroke of the machine. The pawl is operated by a rod 28 connected to an arm 27 of a spindle 26, another arm 18, Fig. 6, of which is urged by a spring 17 so as normally to hold the pawl in the path of the teeth 3a and to apply a non-rotatable brake disc 12 against a disc 7 fixed on the shaft 1 through levers 19 engaging flattened parts of the spindle 26. The nut 3 is thus arrested, producing disengagement of the clutch, and moves axially so as to engage the disc 12 and augment the braking pressure. A plunger 13, Fig. 3, which pivotally supports the pawl 10 and which is urged upwards towards a stop 15 by a spring 14, is moved downwardly by the reaction against the resistance of the spring 14 and compresses oil beneath it. On the stoppage of the shaft, this oil pressure is dissipated gradually through small longitudinal grooves in the plunger, whereby the pressure of the nut against the disc 12 is reduced to that due to the spring 14. On energizing an electromagnet 20, carrying a spring-loaded catch 25 normally engaging the arm 18, the spindle 26 is turned so as to release the brake and disengage the pawl 10 from the teeth, and the clutch engages. On de-energizing the magnet, the spring 17 acts to re-apply the brake and to move the pawl into the path of the teeth. Clutch disengagement occurs inevitably, however, at the end of one revolution, by reason of a cam 29 which operates through a lever 28<1> to disengage the catch 25 from the arm 18. The magnet is controlled by push-button switches 21, 22, and 23 which are arranged in series and which are individually provided with bridging switches 24a, 24b, and 24c. In place of individual bridging switches, a selector switch may be employed, comprising a pair of switch arms A and B, Fig. 8, secured on a shaft fitted with an operating knob, the shaft being normally locked by a spring-urged catch which is releasable only by a key.

Title: Improvements in or relating to the production of noiseless sound film records
IPC: B23K35/36
Filed: 1936-08-12
Abstract: 458,741. Optical sound recording. KLANGFILM GES., 19, Saarlandstrasse, Berlin. Aug. 12, 1936, No. 22176. Convention date, Sept. 9, 1935. [Class 40 (ii)] [See also Group XL] For producing noiseless sound film records, electric sound currents are applied to the recording device through a class B amplifier, and the unidirectional current which flows in the plate circuit of the amplifier is utilized to bias the recording device in dependence on the amplitude of the sound currents. In addition, the unidirectional current may be used to control the amplification of the sound currents. As shown in Fig. 2, the recording device 10 is fed through a transformer by the class B amplifier and, the unidirectional current in the plate circuit K of this amplifier controls the bias of the recording device through a unilaterally conducting device 1 and resistances 2, 3 in conjunction with condensers 4, 9 This plate current also operates through resistances 5, 6, 7 on the grid bias of a preceding valve 8 to control the amplification of the sound currents. The grid bias battery 12 is here arranged across the resistance 7 in such a way that the amplification control operates only when the unidirectional plate current of the class B amplifier exceeds a given value. In a modification, the grid bias battery is in series with the resistance 7, and the amplification control extends over the whole range of amplitudes.

Title: Improvements in or relating to electrical gating circuits
Inventor: NEWBERY GORDON WILLIAM
IPC: H03K17/54
Filed: 1957-07-13
Abstract: 896,461. Discharge tube gating circuits. ELECTRICAL & MUSICAL INDUSTRIES Ltd. June 16, 1958 [July 13, 1957], No. 22256/57. Class 40(6). In a gating circuit for high frequency signals and employing very short gating pulses, the gating pulses contain only frequency components which are lower than those in the high frequency signals to be gated so that the super-imposition of high frequency components from the gating pulses appearing in the gated output of the circuit is prevented. The Figure shows the application to a circuit for gating radar signals at an intermediate frequency of 12 megacycles per second, the gating period being of the order of 1 microsecond, and the signals being of low level, for example 50 micro-volts. As shown the input signals to be gated are applied at transformer winding 4 to push-pull amplifier stages comprising discharge tubes 1, 2 to produce an output in transformer winding 8 only when the tube 3 in the common cathode circuit of tubes 1 and 2 is rendered conductive by the application of a gating signal to its control grid. The original gating pulse 17 triggers a mono-stable flip-flop circuit 16, 16a to "ring" an inductor 27 which is damped by diode 28 to produce a positive going half cycle only of a sinusoidal fundamental frequency derived from pulse 17. This half sine wave is applied via cathode follower stage 36 to produce a gating signal 11 which is applied to the grid of gating valve 3. So as to further minimize the appearance of high frequency components of gating pulses in the output of the gating circuit a differential bias may be applied to the screen grid electrodes of tubes 1 and 2 by adjustment of potentiometer 43. In addition a low-pass filter may be provided between the anode of the tube 3 and the cathode of the tubes 1 and 2.
